WRENCH.

' SPECIFICATION forming part of Letters Patent No. 269,482, dated December 19, 1882.

Application filed April 2(i,188-2. (No model.)

To all whom it may concern Be it known that I, LOYD HUMBOLDT SWAN, of Oxford, in the county of Benton and State of Indiana, have invented a new and useful Improvement in Wrenches, of which the following is a full, clear, and exact description.

My invention relates to a device for tightening the nuts on rail-joints.

The invention consists in a novel construction, arrangement, and combination of a frame adapted to rest on the rail, a wrench or socket engaging with the nut, and provided with a ratchet, and a pawl and lever for operating it, and a pair of arms connected to said frame and engaging with the head of the bolt and with the wrench or socket, so as to hold the apparatus in place and prevent the bolt from turning.

Reference is to be had to the accompanying drawings, formingpart of this specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 isa side view of my invention; and

Fig. 2 is an end view, partly in section. 3 IS an elevation of the crosstie.

All the figures of the drawings represent the Fig.

application of the invention to a railjoint.

A represents the rail, 13 the fish-plate, G the bolt, and D the nut, all of which are of any ordinary description.

E is a metal plate, bent to form an approximate semi-ellipse, and having its ends notched to adapt them to straddle the tread ofa rail, A. About midway of the length of the plate E is attached a bar, E the ends of which form lugs e e at the opposite edges of said plate, which lugs are turned over to form hinge-joints, as shown in Fig. 2. To these lugs are hinged two arms, G G about midway of the length of each. The upper ends of the arms are connected by arod, H, surrounded by aspiral spring, h, the endsof which bear against the inner sides of the arms with a tendency to press their upper ends outward and their lower ends inward or to ward each other. The lower'end of the arm G is provided with asocket, g, which receives the head of the bolt 0, and the lower end of the arm G is forked for engagement with a. device hereinafter referred to.

To the ends of the'plate E are attached the ends of a bar, J, which is bent at obtuse angles from said ends, and has its central portion engaged with and forming a bearing for the outer end of a spindle, K, the inner end of which isprovided with a wrench or socket, L, for engagement with the nut D.

Between the wrench L and the outer end of the spindle K is attached a toothed wheel, M, with which engages a pivoted pa wl,P, carried by a bifurcated lever, Q, the lower end of which has its fulcrum on the spindle K.

-In operating my invention the arm G is placed so that its forked lower end will straddle the spindle K between the Wrench L and the wheel M, and the notched ends of the plate E will bear on the tread of the rail A. The socket g is then engaged with the head of the bolt 0. The parts are'held in such position by the outward pressure of the spring/t. Then by oscillating the lever Q, carrying the pawl P, the operation of the pawl on the toothed wheel M turns the spindle K and wrench L, and tightens the nut D, while the bolt 0 is held fastand prevented from turning by means of the socketg.

The advantages of my invention are: It is readily applied to any rail-joint. The bolt is held tirmly while the nut is being turned. The apparatus is easily operated. It is strong and durable, and not liable to get out of order.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a wrench for fastening rail-joints, the combination, with the upright G, having a. bolt-head socket, g, the upright G having an opposite bearing for the wrench-shaft K, and the socket L, of the shoe E and the cross-tie E as shown and described.

2. The combination of the uprights G G2 and the sockets g L with the shoe E, tie -E and spring h, as shown and described.

3. The combination of the uprightsGG the sockets g L, the shoe E, and tie E with the yoke J and shaft K, as shown and described.

4. The combination of the holding-frame G g G E E J with the ratchet-wrench consisting of a socket, L, shaft K, lever Q, ratchet P, and wheel M, as shown and described.

LOYD H. SWAN.
